Microcosmos: Four Billion Years of Microbial Evolution by Dorion Sagan, Lynn Margulis

4.0

The authors of Microcosmos provide a fascinating look into the role the bacteria have played on Earth, both influencing the larger environment and life itself. Unfortunately, the last two chapters go a bit off the rails, where the authors try to speculate that humans, cooperating with each other in space exploration, will become the equivalent microbes beyond Earth. While I think there is potential with that argument, it just didn't fit with the rest of the book and dragged on for too long.
